SCALE AND POINTER MECHANISM FOR TYPE-WRITER MACHINES.

SPECIFICATION forming part of Letters Patent No. 775,270, dated November15, 1904.

Application filed December 6, 1902, Serial No. 134,112. No model.)

To all whom it may concern:

Be it known that we, I/VILLIAH R. Fox and GLENN J. BARRETT, citizens ofthe United States, residing at the city of Grand Rapids, in the countyof Kent and State of Michigan, have invented certain new and usefulImprovements in Scale and Pointer Mechanism for Type-Writer Machines, ofwhich the following is a specification.

This invention relates to improvements in the scale and pointermechanism for typewriting machines.

The object of this invention is to provide an improved scale and pointermechanism in a type-writing machine which will permit of the easyadjustment of the paper in relation to the scale.

Objects relating to the details of the structure will definitely appearin the detailed description to follow.

\Ve accomplish the objects of ourinvention by the devices and meansdescribed in the following specification.

The invention is clearly defined, and pointed out in the claim.

A structure embodying the features of our invention is fully illustratedin the accompanying drawings, forming a partof this specification, inwhich- Figure 1 is a detail front elevation view of the upper part of atype-writer machine and the carriage when the platen is rocked back toexpose the printing to View, showing our improved scale and pointermechanism in place. Fig. 2 is an end elevation view taken from the leftend of Fig. 1, the twirler being omitted. Fig. 3 is a detail sectionalelevation view taken on the broken line 3 3 of Fig. 1 looking to theright. Fig. 4: is an enlarged detail perspective view of one end of theplatenscale. Fig. is a detail elevation view of the lower corner of theplaten-cradle and the scale-supporting means. Fig. 6 is a detail view ofthe spring for applying pressure to Fig. 7 is a detail transversesectional view through the structure appearing in Fig. 1 to the right ofthe center and looking to the left, showing the platen-roll in theprinting position and showing the relation of the feed-roll and scale.

In the drawings similar letters of reference refer to similar partsthroughout the several views.

Referring to the drawings, A is the top frame of the machine, on whichare carriageways A, supporting suitable ball-bearings, on which thecarriage B reciprocates. The platen O is supported in a suitable cradleG, the same being connected by links G to the carriage, so as to permitit to be swung up for the inspection of the typewritten matter thereon,as indicated in Figs. land 2. Upon the rear platen-cradle stayrod O isalso mounted two collars or sleeves c, to which are fastened theplaten-scale F, formed as shown in Fig. at and having its edge whichcontacts with the platen graduated, the figures reading from left toright, which graduations properly aline with those of the carriage-scaleE. (Clearly appearing in Figs. 1, 2, and 3.) A spring F" (see Fig. 6) issecured to the rear platen stay-rod O and extends upwardly therefrom andrests against the rear of the platen-scaleF to hold the same by gentlepressure against the platen. The scale F is secured by rearwardextensions at each end, which embrace the collars (see Fig. and areretained thereon by suitable screws. (Distinctly appearing in Fig. 3.)

The form of the platen-scale is such that it not only guides the paperand holds it firm at the printing-point, but it also covers thefeedrolls, preventing their becoming soiled by the ribbon and in turnsoiling the paper.

The manner of attaching the scale to the rearstay-rod enables theadjustment for alincment both longitudinally and vertically. Theplaten-scale is curved outwardly, and under it is formed a recess forthe feed-roll H, carried on the shaft H, the same being supported bylinks J. These links J are controlled by the lever J, (see Fig. 7,) thismeans of controlling the rolls being made the subject-matter of ourapplication for patent, Serial No. 131L110, filed December 6, 1902, forapaperfeeding mechanism for type-writers.

across the sheet and inserting it at thispoint,

when the ruling of the page inserted into the platen will exactlycorrespond, and by conforming to this scale thus formed the location ofthe figures or words can be very readily determined.

Mounted on the front rail or on the top of the frame A is adouble-pointed scale-indicator D, the same being cut away at the center,so that one pointer, cl, points to the scale E on the carriage at alltimes, and a second pointer, which is exactly opposite, extends fartherup, so that it is in position to indicate on the platen-scale, thusmaking it possible for the operator to tell at a glance by means of thepointers independent of the scale exactly at what point on the sheet theprinting will occur at the next stroke of the type-bar. When the platenC is rolled down to the printing portion, the pointer (Z is of noparticular utility.

These last four named features are merely described as having beenillustrated in this connection and are not claimed as a part of thisinvention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

In a type-writing machine, the combination of the carriage; a platenthereon; a feed-roll retained yieldingly against the platen, with meansofmanipulating the same; a platenscale, broad, and conformed to embracesaid roll out of contact therewith to shield it from the ribbon andpermit the separation of the feed-roll from the platen before contactingwith the said yielding scale, whereby the contact of the feed-roll withthe paper can be relieved for the ready adjustment of the paper underthe scale, and the feed-roll and scale can both be raised for theconvenient removal and insertion of the paper, as specified.

In witness whereof we have hereunto set our hands and seals in thepresence of two witnesses.
